STATUS: LIVE IN PROD, VERIFIED.

End-to-end smoke test 2026-05-21 against /api/v1/wnba/snapshot/wnba_1042500304 (LV@PHO 2025 final):

  • 0 errors
  • snap.Players count: 18
  • Kahleah Copper: 8 stat diagnostics with flags
  • FIX 1 role-anchor: current_season_min_avg=33.7, historical_min_avg=33.9
  • FIX 4 recent-vs-baseline: recent_vs_baseline_flag=slumping, season_avg=2.6
  • FIX 3 minutes-source: insufficient_data (correctly — WNBA lineup-service doesn't yet provide blended minutes, FIX 3 sees nothing to cross-check)

How it got there (8 commits, 1 session)

In dependency order:

  1. sport-data-service b2dba69 — WNBA wnba_ prefix-strip on Fetch* lookups (reachability fix; rows existed all along)
  2. sport-data-service 043712e — additive Game.Season/HomeRest/AwayRest + Lineup.IsConfirmed alias (cutover-cleanup blocker)
  3. data-hydrator e46210b — Tier 1.1 SDS cutover: fillRosterFromPlayers Players→SportData (+ phantom-roster bugfix)
  4. data-hydrator dbfe7e9 — FIX 5 active-tonight hard gate
  5. data-hydrator dc380de — cache force-refresh respected in singleflight leader + ?refresh=true alias
  6. data-hydrator 9f123df — PropDiagnostic stats list + DvP map league-aware (DiagnosticGameContext.League, statsToDiagnoseFor/dvpStatToCategoryFor)
  7. data-hydrator 90d3bd1 — dispatch attachDiagnostic in assembleMultiSport (no-op gate; integration cliff removed)
  8. data-hydrator f114e9b — hydrateMultiSportPlayerBundles parses boxscore → snap.Lineups + snap.Players → SDS /{league}/stats/player fan-out → bundles populated → attachDiagnostic runs FIX 1-5
  9. data-hydrator 87befcc — roster-fallback when boxscore empty. hydrateFromRosters pulls active rosters from SDS /{league}/players/team/{id} for scheduled/pre-tip games, marks players LineupType="PROJECTED"/Source="roster-fallback", fans out stats. Cold-start guard handles sparse history; FIX 5 active-tonight gate handles surprise inactives.

What still requires follow-up

WNBA scheduled-game snapshots — CLOSED 2026-05-21 by 87befcc. Verified against tonight's GSV @ NYL (wnba_1022600035): 28 players populated via roster-fallback, 20 with prop_diagnostic, lockdown FIX 1-5 firing (Stewart slumping flag on rebounds, Zandalasini huge role-anchor delta 35→6.6, Jonquel slumping flag on points).

Pre-game projections for WNBA: no bundle.Projection populated for WNBA (projections-engine NBA-only today). attachDiagnostic degrades gracefully — line_edges still compute from L10 recency — but the posterior-adjusted projection field stays empty.

Test coverage: the hydrate path is integration-tested via prod smoke; no unit test mocks the SDS client. Acceptable risk profile given (a) it reuses proven NBA mappers, (b) the cold-start guard in ComputePlayerDiagnostic kicks in for sparse bundles, and (c) it's behind a boxscore-existence gate that no-ops for missing data.

What this unblocks

  • WNBA prop picks under the same disciplined methodology as NBA
  • 2025 WNBA final games already have full PropDiagnostic available (replayable for backtests)
  • Tomorrow night's WNBA slate: as games tip and the boxscore populates, PropDiagnostic surfaces in real time
